The figure shows the general arrangement of Laminated
Object Manufacturing. Usually paper sheet with adhesive laminated on one side is used.
Layer fabrication starts with a sheet being adhered to substrate with the heated roller.
The laser traces the outline of the layer. Non-part areas are cross-hatched to facilitate
removal of waste material. Once the laser cutting is complete, the platform moves down and out of
the way and fresh material is rolled into position. The platform moves back up to one layer
below its previous position. The process is repeated.
The prototype part has a
wood-like texture composed of the paper layers. Since moisture is absorbed by the paper,
most models are sealed with a paint or lacquer.
